Abstract: Devices and methods are provided for inducing ventricular growth in a single ventricle patient that include a plurality of anchors spaced apart from one another in an annular configuration; a plurality of springs with respective springs coupled to adjacent anchors around a perimeter of the annular configuration to bias the anchors to expand radially outwardly; and one or more elongate elements extending around the perimeter between the anchors to limit radial expansion of the anchors.

Abstract: Provided is a gearbox for an electric vehicle. The gearbox for an electric vehicle includes a plenary gear revolving around a sun gear and adopts a differential planetary gear method of reducing a rotational speed by using a difference between the numbers of teeth of the planetary gear and the sun gear.

Abstract: A modular approach for strain sensors for large deformations is provided. The strain sensor separates the extension and signal transduction mechanisms using a soft, elastomeric transmission and a high-sensitivity microelectromechanical system (MEMS) transducer. By separating the transmission and transduction, they can be optimized independently for application-specific mechanical and electrical performance. The durability of the strain sensor was evaluated by conducting cyclic loading tests over one million cycles, and the results show negligible drift. Applications of the strain sensor are suitable for human health monitoring as for example an implantable cardiac strain sensor for measuring global longitudinal strain (GLS).

Abstract: A power transmission device includes: a motor to drive a rotary shaft; a first reducer to receive torque from the rotary shaft; a second reducer to receive torque from the first reducer; and a first clutch disposed outside the second reducer to connect and disconnect the second reducer and an external component.

Abstract: Devices and methods are provided for supporting a subject's heart, e.g., to support the left and/or right ventricles of the heart, e.g., to prevent and/or treat heart failure. In one example, the device includes a sleeve configured to be implanted over a region of the subject's heart including a lattice formed on a surface of the sleeve. The sleeve may be positioned and permanently implanted over a desired region of the subject's heart to provide passive support to ventricular tissue of the heart.

Abstract: Devices are provided for mechanically induced ventricular growth in a single ventricle patient that include a body comprising a plurality of springs coupled together to define an open upper end and a closed lower end, wherein the springs surround an interior region of the body sized to receive a portion of a patient's heart. The device may be secured over a portion of a patient's heart, e.g., overlying the left ventricular region, and the bias of the springs may apply strain to the myocardium of the heart to induce ventricular chamber growth.

Abstract: A glove with gecko-inspired dry adhesives is provided to greatly reduce the required grasp force on heavy, smooth items. The orientation of the gecko adhesives is designed to increase shear forces between the glove and the object when lifting and manipulating. The invention additionally equips the non-gripping surfaces of the glove (e.g. back and sides) with a non-adhesive microstructure that prevents the glove from accidently adhering to surfaces during unintentional contact, even when touching otherwise sticky materials such as adhesive-coated automotive panels.

Abstract: An apparatus for controlling an amphibious vehicle includes an engine, a land propeller generating a propulsion force on land, a water propeller generating a propulsion force on water, a power distributor distributing power to the land propeller and the water propeller, a transmission for changing a shift ratio of the power supplied to the land propeller, and a controller, wherein the controller selects and executes one of a land mode for controlling travel on land, a water mode for controlling travel on the water, and a transition mode controlling the travel in a transition region, and the controller maintains an engine output torque in the land mode to be constant and maintains an engine output speed in the water mode and the transition mode to be constant.
